A gold shop owner in central Vietnam gave nearly US$200,000 in gold to a man at her shop Friday, claiming she might have been drugged.

Nguyen Thi Thuy, the owner of Tin Huy gold shop in Quang Ngai Province, said the man first asked to buy a little gold and they exchanged the gold and money.

But after some words with the man, who wore a long-sleeve T-shirt, a helmet and face mask, she took all gold in the trays in front of her, holding around 100 ounces in total, and gave the gold, along with VND1 billion in cash from her safe, to the man, Thuy said.

Cameras at the shop showed that the shop owner had voluntarily put the gold in bags and handed them to the man.

"I didn't know what I was doing," said the 41 year old.

The incident happened in 15 minutes around 10:30 a.m. and other people in the house only knew when Thuy collapsed just when the man left.

"At that time, I was shaking and sweating a lot, then I didn't know anything else," Thuy said.

There was no argument or violence between Thuy and the man, so people thought that was a normal transaction, they said.
